Oh right, that's clever enough...

I had a go at it just now, and I turned the same section into the following.
It seems to work for nothing, --with-ssl and --with-ssl=/foo/path...

  dnl Check for and handle argument to --with-ssl.
  EXTRA_SSL=

  case "$OPT_SSL" in
  yes)
    EXTRA_SSL=/usr/local/ssl ;;
  *)
    EXTRA_SSL=$OPT_SSL ;;
  esac

  AC_CHECK_LIB(crypto, CRYPTO_lock,[
     HAVECRYPTO="yes"
     ],[
     OLDLDFLAGS="$LDFLAGS"
     OLDCPPFLAGS="$CPPFLAGS"
     LDFLAGS="$LDFLAGS -L$EXTRA_SSL/lib"
     CPPFLAGS="$CPPFLAGS -I$EXTRA_SSL/include/openssl -I$EXTRA_SSL/include"
     AC_CHECK_LIB(crypto, CRYPTO_add_lock,[
       HAVECRYPTO="yes" ], [
       LDFLAGS="$OLDLDFLAGS"
       CPPFLAGS="$OLDCPPFLAGS"
       ])
    ])
